Flame inhibitor mixed explosive and preparation method thereof

The invention discloses a flame inhibitor mixed explosive and a preparation method thereof. According to the invention, hexogen is used as an explosive main body, sodium fluoroaluminate is used as a flame inhibitor, 202 rubber and shellac or polyvinyl acetate (PVAc) and shellac are used as binders, and graphite is used as a desensitizer, so that a flame inhibitor mixed explosive provided by the invention has flame elimination capability on the premise of ensuring normal initiation and normal detonation output. Tests show that the free-running property can reach 20 s, the stacking density can reach 0.87-0.88 g/cm , according to a GJB772A-97 402.3 stacking density standard container method, the content of materials between a 20-mesh sieve and an 80-mesh sieve is larger than or equal to 95%, and the content of materials under the 20-mesh sieve and the content of materials under the 80-mesh sieve can reach 15-20%. 一种消焰剂混合炸药及其制备方法，以黑索今作为炸药主体，以氟铝酸钠为消焰剂，以202橡胶和紫胶或聚醋酸乙烯酯(PVAc)和紫胶为粘结剂，以石墨作为钝感剂，使本发明的消焰剂混合炸药，在保证正常起爆和正常爆
